Updated SUMMARY_PROMPT for clarity and conciseness

[Daisuke134]

The SUMMARY_PROMPT in main.py has been updated to provide a clearer and more concise directive to the Self-Operating Computer. This includes more structured instructions and an emphasis on presenting the results succinctly.

Changes made:

• Clarified the execution of user requests by adding "A user request has been executed."
• Increased conciseness by instructing the computer to "Present the results succinctly."
• Emphasized the results by adding the phrase "Display the results clearly."

@Daisuke134 thanks for the PR. This prompt works for me. I am not sure how much the improvement in performance is thought.

I'll monitor and let you know if I have more feedback. I'd imagine we could improve this further.

@joshbickett Thank you so much. I also think that the prompt can improve more. I am wondering how we can evaluate the effect of different prompts on the agent's performance.
